On April 11, 2024, Anbazhagan Subramani defended his PhD thesis entitled \u201cNotched strength and size
effect in pseudo-ductile composite laminates\u201d supervised by Dr. Pere Maimi and Dr. Josep Costa
Balanzat from AMADE – University of Girona.
This PhD research systematically investigates the influence of pseudo-ductility on size-effect behaviour
(reduction of notched strength with increasing specimen size) in composites. While size-effect in FRPs is
known, experimental evidence on pseudo-ductile laminates has been limited to single-notch sizes.
Using finite element modelling, the study uncovered the relationships between pseudo-ductile material
parameters and notched strength. Building on this, design tools were created (based on modifications to
Bazant\u2019s universal size effect laws) to characterise the notched strength of any bi-linear pseudo-ductile
material. These concepts have broad applicability, as demonstrated with plastic hardening materials
containing cracks.
The experimental work employed innovative techniques to characterise the strain non-linearities,
pseudo-ductile strain, and pseudo-ductile damage derived from DIC images of open-hole pseudo-ductile
specimens (single notch radius).
